You or someone else needs to figure out your actual pnl. If you closed everything for a month around year end, the wash sales, of which there no doubt were lots, should net out in the wash so to speak. How big was the 1099 wash sale number in total? Can you give us the total proceeds and basis numbers, roughly as well?
It's entirely possible the broker flagged a wash sale, disallowed the loss, and then did not properly add the wash sale disallowed loss to the basis of one of your other positions. If this keeps happening, you're basically being taxed on all your profits but not getting to net out any of your losses. It could easily result in your situation of a $110k apparent taxable amount despite only having made $80k net as you say.
If they did make a mistake and won't fix it, you should figure out the error/difference and list it as a negative number on your 8949 as an adjustment. you'll end up paying taxes on your correct net gain. But first you have to actually figure out the right amount.
